Principle of Measurement Chapter 1 This chapter gives the principles of the measurements made by the optical modules. The topics discussed in this chapter are as follows: • “Principle of reflectometry measurements” on page 2 • “Principle of optical power and attenuation measurements” on page 4 User Manual 77000010208 Rev.
Page 22: Principle Of Reflectometry Measurements
Chapter 1 Principle of Measurement Principle of reflectometry measurements Principle of reflectometry measurements Optical time domain reflectometry consists in injecting a light pulse into one end of the optical fiber to be analyzed and observing, at the same end, the optical intensity passing through the fiber in the opposite direction to the propagation of the pulse.
Page 23: Validity Of Measurement Itu-T
Chapter 1 Principle of Measurement Principle of reflectometry measurements To locate faults, a reflectometer measures only time. Consequently, group velocity must be introduced in order to determine the distance of the loca- tion. This is done by introducing the refractive index of the fiber into the instrument.
